Abstract

Magnetic, heat capacity and magnetocaloric properties of non-stoichiometric TbMn_0.33Ge₂ compound have been studied. Different measurements show that it undergoes three magnetic transitions at T_N, T₁ and T₂. The magnetocaloric effect has been estimated from magnetization data using Maxwell's relation. The existence of collinear and sine wave modulated components makes the magnetic structure complex at low temperatures. It is also found that this compound shows normal and inverse magnetocaloric effects in different temperature regimes.
